1. An instrument that comprises:
- a sensor that;
determines a performer'"'"'s gesture in the absence of physical contact between the sensor and the performer andconverts an intent of a user into an electrical signal, anddigital logic that is operatively coupled to the sensor and that receives the electrical signal from the sensor and transforms the electrical signal into an audio signal that can be audibly presented to a listener.

Abstract
A musical instrument that can play notes and scale tones without physically touching the device. Microprocessor control, and its associated DSP functionality, permits designer and performer to determine fine musical characteristics and virtual fret positions resulting in a pleasant and playable digital Theremin. Control over key, scale, octave, slew, snap and other characteristics are provided.

14. An instrument comprising:
-
a sensor for determining a performer'"'"'s intent in the absence of physical contact wherein the sensor produces an electrical signal, digital logic that is operatively coupled to the sensor and that receives the electrical signal from the sensor and produces, using the electrical signal, an audio signal that can be audibly presented to a listener, and transforming logic that is operatively coupled to the digital logic and that causes the digital logic to bias the audio signal toward notes of a musical scale.

15. A process for producing an audible waveform, the process comprising:
-
sensing the position of a part of the body of a human user in the absence of physical contact between the part and any sensor, calculating an output frequency based on the position, and generating the audible waveform having the output frequency as a predominant frequency. - View Dependent Claims (16, 17, 18)
